The FEI Tecnai F20 S/TEM is a state-of-the-art field emission gun scanning/transmission electron microscope capable of providing micro- to atomic-scale structural, morphological, and chemical information.

20 - 200 kV operating voltage with Schottky field emission gun ZrO/W source (currently configured for operation at 80 and 200 kV); super-twin objective lens pole piece (Cs = 1.2 mm at 200 kV); single- and double-tilt (hex ring) holders available; 0.34 nm point-to-point resolution in conventional TEM imaging (at 200 kV); 0.24 nm Scherzer resolution in HR-TEM imaging (at 200 kV); 0.16 nm resolution in high-angle annular dark-field scanning TEM imaging (at 200 kV); Fischione Instruments Model 3000 STEM detector; digital imaging via bottom-mounted Gatan UltraScan 1000P camera; EDAX r-TEM super ultra-thin window Si(Li) energy dispersive spectroscopy system (30 square mm detector area) for chemical analysis via detection of X-rays.
